Application of lateral prone position in preventing ventilator associate pneumonia in children

Abstract

Objective To examine the effect of lateral prone position on oxygenation and ventilator associated pneumonia （ VAP） .Methods Totals of 265 patients were randomly divided into the observation group （ n=132） and the control group （ n=133） .The observation group received lateral prone-left lateral-right lateral position, and the control group received supine-left lateral-right lateral position.The incidence of VAP, the duration of mechanical ventilation, the ICU stays and hospital stays were recorded.pH and arterial blood gas were prepared between the two groups.Results The incidence rates of VAP in the observation group and the control were 16.7% and 30.8%.There was a significant difference （χ2 =7.330,P=0.007）.The mortality of the observation group and the control were 6.1%and 19.5%.There was a significant difference （χ2 =10.777,P=0.001）.The duration of mechanical ventilation, ICU stays and hospital stays were （7.55 ±1.87）, （13.57 ± 1.87） and （16.98 ±1.92） days in the observation group, and （13.20 ±4.10）, （19.19 ±4.12）, （23.05 ± 4.42） days in the control group.There were significant differences （ t=14.406, 14.293, 14.459, respectively;P〈0.01）.pH, arterial blood gas, such as PaCO2, PaO2, SpO2 were significantly improved than before in the observation group （t=3.937, 12.673, 17.664, 13.816, respectively;P〈0.05）.Conclusions Lateral prone position can effectively improve the oxygenation, reduce the incidence of VAP, and reduce the duration of mechanical ventilation and hospital stays.
